Blue electroluminescence from ZnSe diodes

摘要

ZnSephyphen;njunction diodes have been formed by nitrogen ion implantation. MIS diodes have also been made using a film of ZnSe oxidized in H2O2solution for the insulator layer. Blue electroluminescence has been observed from both the diodes in forward bias at room temperature. The external quantum efficiency is about 10minus;5. The emission may originate from a bound exciton.
